TYPEWRITING MACHINE.

Application filed February 24, 1919.

T 0 all whom t wia/y concern:

Be it known that I, MANsrinLn CRAW- LnY, a citizen of the United States of America, and a resident of Rutherford, county of Bergen, and State of New Jersey, have invented certain new and useful Improvements in Typewriting- Machines, of which the following` is a specification.

The main features of this invention have relation to `that type ofpower-driven machine disclosed in my former Patent No. 1,156,061, dated October 12, 1915, in which a spring-actuated actuator is employed for actuating the type-bars, and a continuouslydriven motor is employed for pulling back and cocking the actuator after each working stroke thereof, the actuator` being automatically lat-ched back until again released by an operation of one of the character-keys. Y

lt is the special object of the present invention to adapt a ribbon frisket or vibrator mechanism for use on such machine, this mechanism being connected to the actuator in such manner that the working stroke` thereof will raise the ribbon-guide to printing position, the ribbon-guide being thereafter quickly returned to normal, lower position by the act of returning or cocking the actuator-frame by the motor, as more fully hereinafter set forth.

A further object is to provide; a simple color-shift mechanism for use in connection with this type of vibrator mechanism; and a still further object is to provide a simple means for adjusting the vibrating and colorshift devices to compensate for change in case, as more fully hereinafter set forth.

In the drawings- Fig. 1 is a vieW partlyin side elevation and partly in vertical section showing the Vmain features of my device;

Figs. 2, 3 and 4 are views of details hereinafter described;

Fig. 5 is a view partly in vertical section and partly in side elevation showing more particularly the manner of connecting the ribbon-vibrator and case-shift mechanism;

Figs. 6 and 7 are views of details hereinafter more fully described;

AFig. 8 is a transverse vertical sectional' 'view looking rearwardly to show more particularly the manner of connecting my device to the type-bar actuator.

Figs. 9, 10, 11 and 12 are views of details hereinafter described.

Serial No. 278,872.

Fig 13 is a vertical longitudinal sectional view of a typewriting machine illustrating particularly the motor mechanism for retrzcting the type-bar-actuator.

In the drawings annexed, the type-bars a are pivotally connected in the usual manner to t-he type-segment 5, this segment being attached to a part 6 of the frame of the'machine. Each type-bar is provided with a push-coupler 12 which is adapted to be raised into the path of the universal-actuator-bar 27 carried by the horizontal links 2G of the actuator-frame. rThese links 26 are pivotally attached at their forward ends to a pair of depending arms 24; carried by rockshaft- 21 journaled in frame-bars 20; and these links 26 are pivotally carried at their rear ends at the lower ends of another pair of depending arms 25 attached to a rockshaft 22 journaled in said frame-bars 20, a

spring' being coiled around said shaft 22l and connected at its ends to the arms 25 for the purpose of normally tending to throw the actuator forwardly to make an actuating stroke. The construction so far described is the same as in my aforesaid patent and it will be understood that a motor will be provided for retracting the actuator-frame after each actuation and, also that a latchingdevice is employed to latch it in its returned or cocked position. A motor such as substantially shown in my aforesaid `patent is shown in Fig. 13, the retracting link being shown at 18.

` The two rear arms 25 of the actuatorframe are connected rigidly together at their lower ends by a bail-like bar 46 which, about midway its length, is bent upwardly to provide a vertical member 47. Pivotally attached to this vertical member 47 is the rear end of a link 48, whose forward end is pivotally attached to the depending arm of a bell-crank-lever 49, the other arm of this bell-crank being extended forwardly through a slot 50 in the frame-member 6 and having its forward end pivotally Lattached to thelower end of a vertically-slidable ribbon-guide 51. With this construction, it will be observed that with each working stroke of the actuator-frame the ribbon-guide will be raised to printing position and that also with each restoration of the actuator` to cocked position the ribbonguide will be positively and quickly pulled downwardly. To provide for use of this iso Lasl

device on polychrome ribbons, fil connect the rear end ot link i8 to the bar 1li" that 'the pivotal point oli connection may be inoved closer to or Ltarther aivay 4i'roin the airis et movement A(centerco't sliait oi said bai' et?, so as to thereby vary the tliroiv oit said link ltand consequently the lieiffht` to which the ribbon-,guide is raised.V A coni'feiiient way of doing this is to provide the ariii 47 with a longitudinal slot radially arranged with respect to the axis of the shait means being; provided whereby the pivot '12 ci the arm t8 may be held init-s adjusted position anywhere along` said slot.

To adjust and hold the ypivot pin 52 in its adjusted ,position in its slot, provide a vertical linko?) lattached to said pivot at its upper end and pivotally connected :it its lower end to. the one arm 5-t ot the bellcrank, the other, depending, arm ot said .bell-.crank being pivotally,connected to the rod 56 which extends forward `to the keyboard. i To .push orpiill `the rod 56110 thus raise `or lower the pivot 52, lf provide a bellerank pivotally mounted on the under surlof: one ofthe frame-bars ot the keyboard-frame, `one arni 57 ot this hell-crank being pivotally nconnected to saidV rod 56 and the other arni58 being; :pivotally connected Y to 'a link 59 which in turn `is pivotally lconfnected toa linger 60 depending tbroiirli the -ranie-bar of the .machine :ind caried by a rotatably-adjiistable disk Gl which is afilapt- 4 ed-to be held. .in any one of its adjustedpositions by means ot alinger 62 Whichi'esil- ,iently engages in any one oit a series ot notches -63 formed .in the arcuate lookingplate affixed 4to the keyboard-traine lilith this device, the ribbon-vibrating nieclian'isni `maybe readily adjusted to brine; into use any 'one oi". a plurality ofdiitlerent colored vZo'nesyinthe ribbon. In sonic cases, as in stenciling, it is necessary to avoid entirely Vthe raising ofthe ribbon into the path of the itype; to satisfy this need, 'I niakerlhe upper end of the slot inthe ymember 47, open,

so thatf'tlie nivot 52 may be raisedrntirely out oi` theslot and thus disconnected from the actuator entirely, so that movement of the actuator Will, noty be transmitte'dito the ribbon-guider To steady and 'hold the .pivot 52 and its connected partsv when ,thiiscdisyconnected froin'the actuator, I provide a rigid bracket 64 on the 4traine ot the ina- 5 chine, Whose' lower, ed ge isv provided` with a notch Gly-into ywhich the `pivot 52 .enters when disconnected from the actuator, the

Workingin a slotv69 `formed in said bar 65.V

The bar carries a horizontal pin 70 -which works iii an upwardly-and-rearwardly-inclined slot 7l formedin an'arnl 72 pivotally attached to the aforesaid bracket 68 at 73, said arm 72 serving at its forward end as Va i Support tor thepivot 74 oft the bell-crank 49A.' With this construction, it will befob-i served that the vertical movement oit-the case-shift-bar 65 will be imparted to the V pivot 7a` Which is the support for the, bellcrank which yibrates the ribbon, so that the throiv, for Which the device is adjusted will vbe maintained in all positions ci. the platen,

so that-proper vibration of the ribbon will `he brought about irrespective of case. The

bracket-B8 is iiovided with a luv' 75 on which normally rests the arm 72 when the shift. is in lower case.
